Let's divide 871058 by 80
Our goal is to divide 871058 by 80.

On to step 1:
The number 80 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 80

Moving on to step 2:
80 goes into 87 1 times with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 80 from 87 leaves us with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 80

On to step 3:
When dividing 71 by 80, we get 0 with a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 71 leaves us with 71.
Grab the next digit (0) from the dividend, add it to 71, then carry on: 710 / 80

Advancing to step 4:
80 can be fit into 710 8 times, resulting in a remainder of 70.
Write down 8 as next digit of the result. 
Result so far: 108.0
If we take 640 away from 710, we end up with 70.
Append the next digit (5) from the dividend to 70 and continue with: 705 / 80

On to step 5:
705 divided by 80 is 8 with a remainder of 65.
Put 8 as the next digit of the answer. 
Result so far: 1088.0
Deduct 640 from 705 and we're left with 65.
Grab the next digit (8) from the dividend, add it to 65, then carry on: 658 / 80

Advancing to step 6:
658 divided by 80 is 8 with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 10888.0
The remainder is 18 after subtracting 640 from 658.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
The number 80 fits into 180 2 times, leaving a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 10888.2
The remainder is 20 after subtracting 160 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
The number 80 fits into 200 2 times, leaving a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 10888.22
Subtracting 160 from 200 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The quotient of the division is 10888.22, and the remainder is 0.04.
